Objective To investigate post-traumatic stress disorder (PTSD) and life quality (QOL) of children and adolescents with cancer,and analyze the correlation between PTSD and QOL and study whether PTSD would influence QOL.Methods We investigated PTSD by using the PTSD-SS,and investigated QOL by using the EORTC QLQ-C30 V3,and the data was performed by SPSS 17.0.Results The PTSD-SS total score and the scores of EORTC QLQ-C30 of function field and of whole life quality field were negatively correlated,and the PTSD-SS total score and the scores in symptom field and six single measurement of EORTC QLQ-C30 were positively correlated.Conclusions PTSD of children and adolescents with cancer was closely related with the poor functional status and the high level of symptoms problem.PTSD has affected QOL.The higher level the PTSD is,the lower level of QOL will be.

OBJECTIVETo study the correlation between the MRI apparent diffusion coefficient (ADC) value and histological grade and molecular biology of breast invasive ductal carcinoma (IDC).

METHODSThis retrospective study included 125 patients with IDC verified by pathology from February 2010 to February 2013. Conventional MRI and diffusion-weighted imaging (DWI) examination were performed using a 3.0T scanner with diffusion factor of 0 and 800 s/mm(2). The region of interest (ROI) was drawn on the largest lesion and/or its two adjacent slices. The ADC value of the whole tumor was calculated as the mean ADC value. The correlation between mean ADCs and histological grade and biological factors was analyzed.

RESULTSThe mean ADC of pathological grade I, II and III IDC was (1.152 ± 0.072)×10(-3) mm(2)/s, (1.102 ± 0.101)×10(-3) mm(2)/s, and (1.035 ± 0.107)×10(-3) mm(2)/s, respectively. There was a statistically significant difference among them (P = 0.003). Statistically a significant difference was observed between grade III and I (P = 0.034), grade III and II (P = 0.006), but not between grade I and II (P = 0.741). A significant correlation was observed between ADC value and pathological grade (r = -0.342, P < 0.001). The median ADC values were significantly higher in the ER-negative than in the ER-positive cases [(1.130 ± 0.115)×10(-3) mm(2)/s vs. (1.060 ± 0.089) ×10(-3) mm(2)/s, P < 0.001)], in PR-negative than in PR-positive cases [(1.121 ± 0.106)×10(-3) mm(2)/s vs. (1.055 ± 0.096) ×10(-3) mm(2)/s, P < 0.001)], and in Ki-67-negative than in Ki-67-positive cases [(1.153 ± 0.090)×10(-3) mm(2)/s vs. (1.063 ± 0.101) ×10(-3) mm(2)/s, P < 0.001]. A statistically significant correlation was observed between ADC value and expressions of ER, PR, and Ki-67 (r = -0.311, r = -0.317, r = -0.414, P < 0.001).

CONCLUSIONADC value of breast invasive ductal carcinoma is correlated with histological grade, and expression of ER, PR and Ki-67.
